GLSA-201311-21 : cpio: Arbitrary code execution
Medium Nessus Plugin ID 71123
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201311-21 (cpio: Arbitrary code execution)
Cpio contains a heap-based buffer overflow in the rmt_read__ function in lib/rtapelib.c.
A remote server could sending more data than was requested, related to archive filenames that contain a : (colon) character, possibly resulting in execution of arbitrary code or a Denial of Service condition.
There is no known workaround at this time.
SolutionAll cpio users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-arch/cpio-2.11'
